Abstract
Description
Technical Field
[0001] This utility model relates to the field of automation technology, and in particular to an automatic counting device for roll labels. Background Technology
[0002] Roll labels are a type of label material packaged in rolls for easy storage, transportation, and use, and are widely used in product identification, logistics tracking, and other scenarios. Because manual counting of roll labels is inefficient and prone to errors, automatic counting is necessary. Automatic counting devices utilize sensing, mechanical transmission, and electronic technology to accurately count the number of roll labels in real time, significantly improving counting efficiency and accuracy. This provides reliable data support for inventory management and material allocation in the production process, effectively ensuring efficient and orderly production operations.
[0003] The working principle of an automatic roll label counting device mainly utilizes sensors to detect the movement of the labels. When the roll labels move under the drive of the conveyor mechanism, the sensor (such as a photoelectric sensor) detects the passage of a label, generating a change in electrical signal for each detected label. This signal is transmitted to a counter or control circuit, which accumulates the signals to automatically count the number of roll labels. Some devices are also equipped with a display module to present the counting results in real time.
[0004] In existing technologies, some roll label counting devices rely on the principle of light transmission through obstructions to achieve counting. Changes in ambient light can interfere with the counting device, affecting the sensor's accurate judgment of the light transmission through obstructions and leading to counting errors. Therefore, an automatic roll label counting device is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an automatic counting device for roll labels, which aims to improve the existing technology that uses the principle of optical transmission through barriers to achieve counting. However, changes in ambient light can interfere with the counting device, affecting the sensor's accurate judgment of the light transmission of the barriers and leading to counting errors.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An automatic counting device for roll labels includes a base plate, a support plate fixedly connected to the top of the base plate, a sensing block fixedly connected to the rear side of the support plate, a rotating rod fixedly connected to the front side of the sensing block, a transmission tube fixedly connected to the top of the sensing block, a fixing block fixedly connected to the top of the transmission tube, a display screen fixedly connected to the front interior of the fixing block, and a disassembly assembly for quick disassembly of the roll label rotatably connected inside the support plate.
[0008] As a further description of the above technical solution:
[0009] The disassembly assembly includes two rotating rods, which are rotatably connected to the inner wall of the support plate. An inner shell is fixedly connected to the front side of each rotating rod, and a fixed rod is slidably connected inside the inner shell. Two limiting blocks are slidably connected to the outside of the fixed rod. A rotating plate is fixedly connected to the front side of each of the two limiting blocks, and a spring is fixedly connected to the opposite side of each of the two rotating plates.
[0010] As a further description of the above technical solution:
[0011] Two limiting rings are fixedly connected to the outside of the rotating rod, and the outside of the rotating rod is rotatably connected to the inside of the support plate.
[0012] As a further description of the above technical solution:
[0013] A control plate is fixedly connected to the top of the base plate, and a force-applying column is slidably connected to the top of the control plate;
[0014] As a further description of the above technical solution:
[0015] A motor is fixedly connected to the rear side of the support plate, and the rear side of one of the rotating rods is fixedly connected to the front side of the motor.
[0016] As a further description of the above technical solution:
[0017] A fixing plate is fixedly connected to the bottom of the motor, and the front side of the fixing plate is fixedly connected to the rear side of the support plate.
[0018] As a further description of the above technical solution:
[0019] The inner wall of the inner shell is fixedly connected to a rotating shaft, and the inside of the rotating plate is rotatably connected to the outside of the rotating shaft.
[0020] As a further description of the above technical solution:
[0021] The inner shell is fixedly connected to a fixed column on the outside, the front side of the fixed rod is fixedly connected to a fixed disk one, and the rotating rod two is fixedly connected to a fixed disk two on the outside.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this invention, the rotating rod rotates, causing its sensing block to receive the rotation signal. The number of rotations is then transmitted to the fixed block via a transmission tube. The fixed block then displays the number of rotations on its screen, thus achieving automatic label counting. Furthermore, this significantly improves counting efficiency, enabling the counting of a large number of labels and saving labor and time costs.
[0024] 2. In this utility model, the fixed rod moves backward, thereby causing its limiting block to disengage from the fixed rod. The rotating plate rotates, causing its spring to compress. The fixed rod then rotates, causing its fixed rod to disengage from the inner shell, thus achieving quick disassembly of the reel. In addition, it facilitates the operator's inspection, maintenance, and replacement of the reel, reducing the difficulty of operation and labor intensity, thereby improving the maintainability of the equipment and extending its service life.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 2 and Figure 3 This utility model provides an embodiment of an automatic counting device for roll labels, including a base plate 1, which is the foundation of the entire device and is used to support the device. A support plate 2 is fixedly connected to the top of the base plate 1, which supports and fixes the components so that they can operate normally. A sensing block 3 is fixedly connected to the rear side of the support plate 2, and a rotating rod 5 is fixedly connected to the front side of the sensing block 3. A transmission pipe 4 is fixedly connected to the top of the sensing block 3, and a fixing block 6 is fixedly connected to the top of the transmission pipe 4. A display screen 7 is fixedly connected to the front interior of the fixing block 6. The sensing block 3 receives the number of rotations of the rotating rod 5. The rotating rod 5 receives external force and rotates accordingly. The transmission pipe 4 receives the signal and transmits the signal to the fixing block 6. The fixing block 6 supports the display screen 7 and also transmits the signal to the display screen 7. A disassembly component for quickly disassembling the roll is rotatably connected inside the support plate 2.
[0033] Reference Figure 2 and Figure 4 The disassembly assembly includes two rotating rods 8, which are externally rotatably connected to the inner wall of the support plate 2. The rotating rods 8 receive the rotation of the motor 20 and thus rotate. An inner shell 10 is fixedly connected to the front side of the rotating rods 8, and the inner shell 10 protects the internal disassembly assembly. A fixed rod 11 is slidably connected inside the inner shell 10. Two limiting blocks 15 are slidably connected to the outside of the fixed rod 11. A rotating plate 12 is fixedly connected to the front side of each of the two limiting blocks 15. A spring 14 is fixedly connected to the far side of each of the two rotating plates 12. The fixed rod 11 slides inside the inner shell 10. The limiting blocks 15 limit the fixed rod 11, preventing it from moving within the inner shell 10. The rotating plate 12 receives the pushing force of the limiting blocks 15 and thus rotates. The spring 14 receives the pushing force of the rotating plate 12 and thus returns the spring force to the rotating plate 12.
[0034] Reference Figures 1 to 3Two limiting rings 22 are fixedly connected to the outside of the rotating rod 5. The limiting rings 22 prevent the rolled label from detaching from the rotating rod 5 during operation. The outside of the rotating rod 5 is rotatably connected to the inside of the support plate 2. The rotating rod 5 transmits rotation to the sensing block 3. A control plate 18 is fixedly connected to the top of the base plate 1. A force-applying column 19 is slidably connected to the top of the control plate 18. The force-applying column 19 receives external force, thereby moving the control plate 18 and stopping the equipment. A motor 20 is fixedly connected to the rear side of the support plate 2. The rear side of one of the rotating rods 8 is fixedly connected to the front side of the motor 20. The motor 20 drives the rotating rod 8 to rotate, thereby... The label is rotated. A fixing plate 21 is fixedly connected to the bottom of the motor 20. The front side of the fixing plate 21 is fixedly connected to the rear side of the support plate 2. The fixing plate 21 fixes the motor 20, stabilizing it and enabling it to transmit power. A rotating shaft 13 is fixedly connected to the inner wall of the inner shell 10. The inside of the rotating plate 12 is rotatably connected to the outside of the rotating shaft 13. The rotating shaft 13 allows the rotating plate 12 to rotate around it. A fixing post 9 is fixedly connected to the outside of the inner shell 10, separating the label from the inner shell 10. A fixing disc 16 is fixedly connected to the front side of the fixing rod 11, and a fixing disc 27 is fixedly connected to the outside of the rotating rod 28. Both the fixing disc 16 and the fixing disc 27 limit the width of the roll-shaped label, but the fixing disc 16 can be disassembled.
[0035] Working principle: The operator places the labels on the reel and starts the motor 20. The motor 20 drives the rotating rod 8 to rotate, thus moving the labels on the reel and causing the rotating rod 5 to rotate. The sensor receives the number of rotations of the rotating rod 5, which is then transmitted to the fixing block 6 via the transmission tube 4. The fixing block 6 then transmits the signal to the display screen 7, showing the number of rotations. When the required number of rotations is reached, the operator presses the force application column 19, stopping the equipment and thus achieving automatic label counting. Furthermore, it significantly improves counting efficiency, enabling the counting of a large number of labels, thereby saving labor and time costs.
[0036] After the equipment stops, the operator holds the fixed plate 16 and moves it forward, which moves the fixed rod 11 forward, causing the limiting block 15 to move. This drives the rotating plate 12 to rotate, causing the spring 14 to compress. Rotating the fixed rod 11 disengages it from the inner shell 10. The finished product is then removed, and the fixed rod 11 is placed back inside the inner shell 10. The limiting block 15 then locks the fixed rod 11 again, thus achieving quick disassembly of the reel. In addition, it facilitates the operator's inspection, maintenance, and replacement of the reel, reducing the difficulty of operation and labor intensity, thereby improving the maintainability of the equipment and extending its service life.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
